The endoplasmic reticulum (ER) is the main site for protein folding, lipid biosynthesis and calcium storage in the cell. Disturbances of these critical cellular functions lead to
ER stress. The ER responds to disturbances ...

This PhD thesis describes cellular responses to the induction of endoplasmic reticulum (ER) stress, focusing on the role of autophagy and cell death. Pro-survival role of unfolded protein response (UPR) is analysed by ...

A build-couple-pair strategy, including double-reductive amination macrocyclization, has been used to generate decorated macrocycles (eannaphanes) with an embedded triazole and monosaccharide. Biological screening led to ...

Global downregulation of microRNAs (miRNAs) is a common feature of human tumors and has been shown to enhance cancer progression. Several components of the miRNA biogenesis machinery (XPO5, DICER and TRBP) have been shown ...

Endoplasmic reticulum (ER) stress-induced cellular dysfunction and death is associated with several human diseases. It has been widely reported that ER stress kills through activation of the intrinsic mitochondrial apoptotic ...

Endoplasmic reticulum (ER) stress is a feature of secretory cells and of many diseases including cancer, neurodegeneration, and diabetes. Adaptation to ER stress depends on the activation of a signal transduction pathway ...

In response to diverse stress stimuli, eukaryotic cells activate a common adaptive pathway, termed the integrated stress response (ISR), to restore cellular homeostasis. The core event in this pathway is the phosphorylation ...

In chronic lymphocytic leukemia (CLL) the proliferation rate and resistance to drug-induced apoptosis are recognized as important factors in the outcome of treatment. In this study, we assess the activity and the mechanism ...

During apoptosis, the process of mitochondrial outer membrane permeabilization (MOMP) represents a point-of-no-return as it commits the cell to death. Here we have assessed the role of caspases, Bcl-2 family members and ...

The endoplasmic reticulum (ER) is the site of folding of membrane and secreted proteins in the cell. Physiological or pathological processes that disturb protein folding in the endoplasmic reticulum cause ER stress and ...

Background: Glucose and oxygen deprivation during ischemia is known to affect the homeostasis of the endoplasmic reticulum (ER) in ways predicted to activate the unfolded protein response (UPR). Activation of UPR signalling ...

Autophagy is tightly regulated by the unfolded protein response (UPR). It plays an important role in the removal of unfolded proteins, damaged mitochondria and expanded endoplasmic reticulum (ER), to help relieve ER stress ...

Nerve growth factor (NGF) is well characterised as an important pro-survival factor in neuronal cells that can inhibit apoptotic cell death upstream of mitochondrial outer membrane permeabilisation. Here we addressed the ...

Nerve growth factor (NGF) is a potent pro-survival growth factor that has diverse roles in development and in the adult nervous system. It has two cognate receptors that stimulate distinct signalling pathways, tropomyosin-related ...

Acute myeloid leukemia (AML) is an aggressive stem cell malignancy that is difficult to treat. There are limitations to the current treatment regimes especially after disease relapse, and therefore new therapeutic agents ...

The tumour necrosis factor family member TNF-related apoptosis-inducing ligand (TRAIL) selectively induces apoptosis in a variety of cancer cells through the activation of death receptors 4 (DR4) and 5 (DR5) and is considered ...

Tumour necrosis factor-related apoptosis-inducing ligand (TRAIL) is a cytokine and a selective inducer of apoptosis in a range of tumour cells, but not in normal, untransformed cells. A large number of chemotherapeutics ...
